To all whom it may concern.-

Be it known that 1, CHARLES E. ONGLEY, a citizen of the United States, residing at New York city, in the county and State of New York, have invented a new and useful Improvement in Electrical Signal Systems, (Case 1,) of which the following is a specification.

My object is to constructan apparatus by means of which a signal or other device having several operating-magnets may be operated by use of a single line-wire, said magnets being separately energized in the desired order; and the invention consists in a device for throwing any one of several magnets at a receiver into an operative circuit at will, and in combinations of devices embodied 111 such apparatus.

In the accompanying drawings, Figure 1 is diagram of a system embodying the invengzn. Fig. 2 is a view of the propelling mech- Fig. 3 is a plan or a portion thereof, and Fig. i is a detail of the switch-contacts. I

1 1s a line or circuit wire leading from any suitable transmitter or transmitters placed at any desired points andindicated at 1-for example, at the stations along a 'railroad the receiver being at the main railroad oflice, or the transmitters may be placed at firealarm stations, the receiver being located at theoffice of the fire department; but I do not limit myself to using the present improve ment 1n connection with these particular systems, since it is of broader application. In line 1 is included a relay-magnet 2 and a battery MB, and in the form illustrated the relay-magnet is in a normally-closed circuit, and one of the local circuits hereinafter described is closed by each movement of the relay-magnet; but it is evident that a reversal of this arrangement might be made to operate equallywell. The armature 3 of the relay is connected by wire 4 to the local battery LB, and thence by wire 5 to wire 6 to magnet 7, which is the first magnet to be operated in the receiver R. The receiver shown is a diagrammatic View of a well-known form of recorder, the armatures of magnets 7 7, 850., each controlling a type-wheel and the magnet 17 be- 5 ing the printing-magnet. Above cach magnet of the receiver are shown in the drawings a type-wheel t and an attached ratchet-wheel r, with which a propelling-pawl moved by the armature of its magnet engages, as is common in this class of devices. It will be evident that the several magnets may be utilized for operating other devices than those here shown. From magnet 7 wire 8 extends to the starting-magnet 9, and thence to the contact 10. From this point the circuit is continued through the movable co-operatin g contact 11 to the frame of the mechanism, wire 12, contact-raising magnet 1 3, and back to the second contact 1a of the relay. The contact is connected in similar manner to the second magnet of the receiver, 10 to the third magnet, and so on for succeeding contacts. The last two contacts 15 are in the following circuit: wire 16, through the printing or other similar magnet 17, to local battery, wire 18, to the stopping-magnet 19, and back to the second contact 15.

Referring now to Figs. 2 and 3, the mechanism of the device which I term an automatic distributer or switch will be described. Any suitable motor mechanism is employed. This mechanism is normally held from movement by means of the detent-armature and pawl 21, which, when the apparatus is at rest, occupies the position shown in Fig. 2.

2 is a weighted escapement controlling the rapidity of movement of the mechanism.

23 is a screw turned by the motor during its operation. Adjacent to the screw is the contact- 11, loosely pivoted or sleeved on the axis 2%. Said contact carries a pin 25, which rides in the thread of the screw, whereby as the screw turns the contact is moved bodily along the length of the screw. It is evident that this arrangement may be varied somewhat. For example, contact 11, instead'of moving bodily on the rod 2i, may be hinged or supported on a spring at the rear end, and its contact end may movein the arc of acircle.

26 is an armature, an extension of which bears on one end of the contact lever 11. When, therefore, the armature is attracted, the pin will be raised from the screw-thread, at the same time leaving the lower contact 10.

27 is a cord connected to the movable arm 1.1, and, passing over a pulley 28, is connected with a weight sliding t'reelyin atubefltl, thus serving as a retracting device for 11. when it is raised from the screw. A spring or other retracting device might be employed. Over the several contacts 10". &c., is placed a track or way 30, having an inclined end 31 adjacent to the end contacts 15, and over each of the contacts 10', the, near one edge, as shown, is placed a depending arm or stop 32. The first contact 10 is provided with a similar stop 38. At the outer end of screw 23 is placed a disk or plate 34, preferably being capable of lengthwise. movement by the compression of the spring and having a projecting pin 35, for a purpose which will hereinafter appear.

The operation of this system and apparatus is as follows: Let it be supposed that in line 1 is a transmitter constructed to break and make the circuit twice in succession, then after a comparatively long pause to break it again, then after another pause to break it twice, thus sending over the line the signal 21.2. The eilect of the iirst break would be to close the circuit 3, 4-, L13, 5, (3, 7,8, 9,10, 11.12, 13, and 14. This closure energizes magnet 7, which in the present case is supposed to operate a type-wheel in a recorder, but which may operate a numbered disk in an annunciator or indicator or any other suitable rceeiving device. At the same time magnet 9 pulls down the detent 21, allowing the motor to operate. At the same time, also, magnet 1-3 attracts its armature, raising arm 11, breaking the circuit at 10, allowing the armatures of magnets 7 and 13 to move back to their original positions. As soon as this arm is raised the weight pulls it against the stop \Vhen the line-circuit is re-cstablished by the spring passing off the first insulating-space of the signal-wheel, the relay-armature is again attracted. The movement of the armature 26 allows arm 11 to again come into working contact with screw 23, whereupon said screw begins to carry the arm along toward contact 10'; but before said contact is made the local circuit is opened at the relay, so that magnets 7and 13 will not be again energized m1- til the transmitter closes the circuit at the relay. The mechanism is so adjusted that arm 11 will not travel off of the contact on which it rests during the interval between two of the quicl zly-succeeding breaks and makes of the transmitter. llenco when the second break occurs and the relay is closed contact 11 is still resting on contact 10, and consequently magnets 7, 9, and 13 will be again energized, magnet 7 moving the typewheel or the other device a second space, magnet 9 accomplishing nothing, since its armature is already attracted, and magnet 13 again raising arm 11, allowing it to return against stop 33. Then when the circuit is opened at the relay the screw again carries arm 11 forward, as before described. In the example which we are supposing a comparatively long interval succeeds before another first stop 33, instead of against stop 3 since arm 11 has had time to move along onto contact 1.0. Next follows a long space before succeeding breaks and makes of the circuit by the transmitter. This allows the screw to carry armll along into line with contact 10". Consequently when the next break and make occurs at the transmitter it will close the re lay-circuit as follows: 3 -1- LB 5 (i 7 Sf, to contact 10, and back to the relay. This moves the third type-wheel one space and raises arm 11 from the screw, allowing it to move back against the second stop Then follows another break and make at the trans mitter, moving the same type-wheel a second space. The type-wheels having thus been arranged to indicate the desired signal,the transmitter ceases to operate, and arm 11 is moved along by the screw into line with the final contacts 15 and electrically connects the same. This closes the following circuit: battery LB, wire 18, magnet 19, lower contact 15, upper contact 15, wire 16, magnet 17, and back to the battery. This energizes magnet 17, which in the present instance is supposed to be the printing-magnet of the recorder. It also energizes magnet 19, moving its detent-armature back into the position shown in Fig. 2, thereby stopping the motor it. Before this occurs, however, the pin on plate 3t is brought in its revolution with the screw under the arm 11, raising the arm above the lower end of the inclined portion 31 of the track 30. Arm 11 is notched on one side, so that the pin shall not strike the arm in its downward motion, but shall be allowed to revolve and come against the arm on the opposite side of the screw.

It will be evident that any number of typewheels may be used in the recorder, that they maybe each operated in succession or in any desired order, and that all these may be 0perated by the use of a single line-wire, and that the failure or disarrangement of any part of the receiving apparatus would not break. or disturb the main line.
